One Tree Island

A Wireless Sensor Network was deployed at One Tree Island in late 2008 and consists of a base station (star on the map) located on the island itself and three network poles (diamonds on the map) one in each of the main lagoons that make up the reef. The design reflects the need to understand lagoonal flushing both in the main lagoon and the three sub-lagoons that make up the main lagoon. The data is paired with deep water moorings located 7km to the west and east of the island to look at the influence of oceanic water on the lagoon of One Tree Island.

Each pole is located in a small 'micro-atoll' or circular structure with the pole in the middle and a thermistor string running from the pole across the floor of the atoll to the outer wall and then down the atoll wall into the lagoon.

Each pole supports a thermistor chain measuring temperature profiles within the lagoons, the pole at RP3 also has a weather station. Above water light (as Photosynethically Active Radiation – PAR) is also measured using a sensor located on the island.

The wireless sensor networks are supported by the Island Research Stations under the Tropical Marine Network (TMN) banner. Partners include the University of Queensland which run the Heron Island Research Station, the University of Sydney which run the One Tree Island Research Station, James Cook University which run the Orpheus Island Research Station and the Australian Museum that run the Lizard Island Research Station.

The Facility had significant initial funding from the Queensland State Government via the Department of Science, Information Technology and Innovation.

The Facility also was a partner in the ARC Intelligent Sensors, Sensor Networks and Information Processing (ISSNIP) project.

The Facility is a founding member of the Coral Reef Ecological Observation Network (CREON) and is a participant in the Ocean Data Interoperability Platform project (ODIP).

Your access to IMOS Argo data discovery and exploration is through the Australian Ocean Data Network (AODN) Portal.
